If you have better recipe sorting enabled and are trying to use the recipe book to craft multiple blocks, the sorting by recently used recipes function will move the recipe that you're currently clicking away from your cursor while you're crafting.

Suggestion: Don't sort by recently used recipes within recipes that are already craftable. Or include an option for disabling sorting by recently used recipes. I don't think it's particularly needed as long as the recipes are sorted by craftable. The limited amount of currently craftable recipes should make finding the recipe you're looking for easily findable already.
